Jenny Nishida, 41, is a former employee of the Oahu Transit Services' Employees Federal Credit Union. She admitted to making 122 false Visa payments to herself that totaled over $358,000.

An alert auditor caught the discrepancies in 2012, which then triggered a full federal investigation.

Nicole Cheung, 34, admitted to embezzling close to $17,000, while former manager Dona Takushi pleaded guilty last week to embezzling over $100,000.

The FBI says it appears all three women were running the same scam without the others knowing it.

"In this case, it's the employees of TheBus and their family members. So, when you steal from a credit union, you're really stealing from your own affinity group, which never really made a whole lot of sense to me," said Tom Simon, FBI spokesperson.

Each of the women face up 30 years in prison; Cheung and Takushi face sentencing in August.
